2 LSD's for 8.4 rear

3rd member with trd sport LSD. I bought it and never installed it before I sold my truck. $300

Also have a Eaton LSD that was never installed as well, brand new. $400 this fits in a flat rate box, so I'll cover shipping.

And finally, I have the rebuild kit for the LSD. I was going to rebuild the third member with the TRD sport LSD before installing it to make sure it was new and good to go. $100

Located in Virginia. Can ship on your dime

 

Interested in the Eaton, does it required the rebuild or does the TRD LSD need the rebuild?

 

The eaton is brand new and does not require a rebuild.
The trd one may not need it either, I just bought the kit to do it before I installed it to make sure everything was new and I wouldn't have to do it again.

 

Ok, is the eaton a clutch style or their newer true-track gear style LSD? What would shipping look like to 85233 (Az)?

 

this. He beat me to it. I’m also curious if this is the 4.10 or 3.73 gears.

 

Probably the 4.10/factory trd gear ratio? According to the product ID number, it's the trutrac style.

Geared, which means it still requires a little bit of traction on the spinning wheel to actually work, which is great for off-road, but if you plan to street it more often, clutch based posi is the way to go.

 

That’s got 3.73 gears unless somebody regeared it. ALL 2nd gen LSD diffs have 3.73 gears.
Check the markings on the side of the crown gear

 

Why do you say that?

 

For the trutrac to actually engage, the other free spinning wheel needs some sort of traction, either some brake application or hand brake application to get it moving, which is perfectly fine out on a trail or crawling.
Clutched based posis are always engaged just like a locker but have clutch packs to allow for slip during cornering, that’s why I always suggest posis, even if they do require different maintenance and wear faster. Both are good for road use, anything is better than the dreaded open diff.

 

I see EATON ONLY on the rebuild kit, I assume that's as self explanatory as I think it is meaning that kit cannot be used to rebuild the factory LSD?

Do you know what year the third member is out of? Is it the non locker version?
